EU data is subject to a 12GB monthly fair-use limit, while usage outside included European destinations requires an Out of Plan add-on.</p><p>Smarty may also suspend your service if it identifies that you've used it outside the UK continuously for 60 days or longer within a rolling 12-month period. It's intended primarily as a UK mobile service rather than a SIM for extended stays overseas.</p><ul><li><a href="https://smarty.co.uk/all-plans" target="_blank">Shop the full Smarty range of SIM plans</a></li></ul> </article> ]]>
